Cissampelos pareira L., belonging to Menispermaceae family, has worldwide distribution, occurring intropical and subtropical regions of the Americas, Africa and Asia. It is the most popular species of Cissam-pelos, known for its medicinal uses of leaves and roots. The study aims to find distinctive leaf anatomicalcharacters, and also demonstrate the importance of spectral data to identify C. pareira samples, in order tocontribute to its taxonomy and quality control of its drugs. Anatomical leaf analyses were performed byoptical and scanning electron microscopy. The spectral profile was obtained from methanolic extracts ofC. pareira samples from Brazil and Africa, with application of UV–vis spectrophotometry data, which wereanalyzed by principal component analysis (PCA).

walls, stomata, trichomes, mesophyll, features of midrib and petiole, and the spectral profile within thewavelength ranging between 770 and 240 nm (eight bands) differs between Brazilian and African sam-ples. The results represent an additional support to the taxonomy of C. pareira, and the quality control oftheir leaf drugs, mainly in relation to misidentified samples.

ntroduction
Cissampelos pareira L., belonging to Menispermaceae family,as worldwide distribution, occurring in tropical and subtropicalegions of the Americas, Africa and Asia (Ortiz, 2001). In Brazil,t is encountered in different types of vegetation, from Caatinga,tlantic Forest and Amazon forest (Braga, 2015). According tochmelzer and Gurib-Fakim (2008), in Africa this species occursn subtropical forest, savannah, deciduous shrubs, often persistingn cleared land and plantations, also in secondary vegetation andear rock outcrops.
It is the most popular species of Cissampelos not only for its wideistribution, but mainly because its leaves and roots are widelysed as medicinal. According to Napralert (2013), C. pareira hasore than eighty folk names. In Brazil, it is known as “parreira”,
abuta”, and “parreira-brava” (Lewis and Elvin-Lewis, 1977; Rury,983); in Africa, it is called in folk medicine as “chegonde” and
karigi-munana” (Hedberg et al., 1983; Rukunga et al., 2009); and inndia, it is known as “ambastha”, “patha” and “laghupatha” (Vaidya,988).∗ Corresponding author.E-mail: [email protected] (M. de Fátima Agra).

In many ethnobotanical reports, the leaves of C. pareira are rec-ognized as a natural medicine for various purposes. The leaf juiceis used as antiseptic, anthelmintic, insecticidal and parasiticidal,and against dermatitis (Singh and Ali, 1992), asthmas (Singh andMaheshwari, 1994), genitourinary disorders (Sanchez Medina et al.,2001), diarrhea, dysenteries and gastrointestinal disorders (Kumaret al., 2006; Kamble et al., 2008), antifertility (Ganguly et al., 2007;Priya et al., 2012), and antidiabetic (Yadav et al., 2013). The topicaluse of leaves is indicated to treat hemorrhages from cuts, burns andwounds (Ramasubramaniaraja and Babu, 2010; Shukla et al., 2012),and also to treat abscesses (Abbasi et al., 2010; Haque et al., 2011). Inaddition, in India, the leaves are also used as cattle feed to increasemilk production, and also in some food systems as thickeners,gelling agents, texture modifiers and stabilizers (Vardhanabhutiand Ikeda, 2006; Priya et al., 2012), inter alia.
The leaves of C. pareira have been reported to be a richsource of isoquinoline and bisbenzylisoquinoline alkaloids (Shuklaet al., 2012), such as berberine (Kupchan et al., 1960a), curine(Chowdhury, 1972), hayatine (Sharma, 1987) and magnoflorine(Ahmad et al., 1992). In addition, have also been isolated essen-
tial oil (Kupchan et al., 1960b), flavonoids (Ramirez et al., 2003;Amresh et al., 2007a), polysaccharides (Vardhanabhuti and Ikeda,2006), and pectin (Singthong et al., 2004; Arkarapanthu et al., 2005)have also been isolated.Ltda. All rights reserved.

Biological and pharmacological activities of leaves and aerialarts (leaves and branches) of C. pareira were demonstrated
n several studies. The cissampeloflavone, isolated from leaves,howed activity against Trypanosoma cruzi and T. brucei rhodesienseRamirez et al., 2003). The plant extract exhibited antifungal activ-ty against Aspergillus niger and Saccharomyces cerevisiae (Kumart al., 2006). The ethanol extract of the aerial parts showed anti-nflammatory and analgesic activities (Amresh et al., 2007b). Theontraceptive and cytotoxic effects were demonstrated by Priyat al. (2012) and Ganguly et al. (2007), respectively. The anti-iabetic activity was confirmed by Jannu et al. (2011) and Yadavt al. (2013). In addition, a preliminary study carried out by Thakurnd Rana (2013) confirmed the anxiolytic effect of C. pareira leaves.
According to Rhodes (1975) and Hoot et al. (2009), C. pareiraas problems in its interspecific delimitation with imprecise limits,ainly caused by its wide distribution and great plasticity of their
egetative forms. On the other hand, the leaf anatomical studiesave shown to be an additionall support to the plant taxonomy, aslready done in Solanum (Nurit-Silva et al., 2007; Nurit-Silva andgra, 2011; Sampaio et al., 2014), and also to the Menispermaceae
amily, including Cissampelos by De Wet et al. (2002), Porto et al.2008, 2011, 2012), for example.
The spectroscopic chemical techniques have emerged and con-ributed as an additional tool to contribute to plant taxonomy, andlso as a support to the quality control of herbal drugs, allowingnformation to be obtained without the need for previous isola-ion of chemical constituents, as demonstrated before for Baccharis
Lonni et al., 2005) and Solanum (Basílio et al., 2012).Although the leaves of C. pareira are commonly used in tradi-ional medicine, and there is evidence of many activities of theirompounds, a literature survey showed a lack of studies of the
able 1elected voucher specimens of Cissampelos pareira and species of outgroup.

leaf comparative anatomy, as well as spectroscopic analysis ofUV–visible of the leaf extracts. In this way, this study aimed to findleaf anatomical characters, distinctive to C. pareira, on samples ofplants from Brazil and Africa, revealing the importance of anatom-ical studies combined with spectral data, would be useful to thequality control of its drugs, as well as to the taxonomy of C. pareira.
Materials and methods
Plant material
Botanical expeditions and field observations were carried outby N.M. Porto, in areas of Atlantic Forest and Rain Forest, for sam-ple collection of Menispermaceae, including leaves of Cissampelospareira L. in the following Brazilian States: Alagoas, Pará Maranhão,Paraíba, Pernambuco and Sergipe (Table 1). For each individual, anaverage of three leaf samples were taken from the second to thefifth nodes of the leaf blades and the proximal, median and distalportions, and petiole were fixed in FAA (50%) for 24 h (Johansen,1940), and preserved in ethanol 70 GL. The other part of fertilematerial was pressed and dried for herbaria, according to Bridsonand Forman (1999). The voucher specimens were deposited at theHerbarium Prof. Lauro Pires Xavier (JPB), of the Universidade Fed-eral da Paraíba.
In addition, leaf samples from herbarium specimens identi-fied as C. pareira were also analyzed from the following herbaria,acronyms by Thiers (2015): Herbarium of Centro de Pesquisas

natomical and histochemical analysis
The plant material was divided in two portions, one for anal-sis by optical microscopy and the other by scanning electronicroscopy (SEM). Transverse sections were performed on leaves
f C. pareira by free hand using commercial razor blades. Subse-uently, the sections were cleared by sodium hypochlorite (20%)ntil complete clarification, neutralized with acetic acid (0.2%),ashed in distilled water, and stained with a solution of Astra blue
nd Safranin, modified by Bukatsch (1972). Leaf epidermis waseparated from the mesophyll by dissociation in Jeffrey solutionJohansen, 1940), and then stained with Safranin with 1% solutionn 50% alcohol, according to Franklin (1945).
For alkaloid detection, transverse sections were treated withittman’s and Wagner reagents (Furr and Mahlberg, 1981). All leaf
ections were mounted in glycerinated gelatin (50%). The obser-ations and microphotographs were performed by a photomicro-cope (Leica DM750), with image processing software (Qwin Sys-em) coupled to a video camera (Leica ICC50 HD) for image capture.
canning electron microscopy (SEM)
Scanning electron microscopy (SEM) of leaf epidermis was per-ormed in dry material to optimize the observation of waxes andpidermal appendages. Leaf fragments of 1 cm2 were fixed in aolution of 4% glutaraldehyde in 0.1 M potassium phosphate buffer
pH 7.0) for 24 h, at 48 ◦C, then washed in 0.1 M sodium cacody-ate buffer (pH 7.0), followed by post fixation in 1% OsO4, in 0.1 Ma-cacodylate buffer (pH 7.0) for 1 h, at room temperature. Subse-uently, the fragments were dehydrated in a crescent ethylic series,ig. 1.

and dried at the critical point, placed on aluminum stubs withdouble-sided tape, air-dried and, finally, coated with gold. Finally,photomicrographs and microscopic analysis were performed byscanning electron microscopy (JEOL JSM-5600), on leaf epidermis,at an accelerating voltage of 15 KV. Micromorphological character-ization was complemented by the analysis of epicuticular waxes ofthe leaf epidermis that were classified here according to Barthlottet al. (1998).
Chemical analysis
Samples of dried leaves of C. pareira (from Brazil and Africa)and of nine species used as an outgroup of Menispermaceae fam-ily were investigated: Cissampelos andromorpha DC., Cissampelossympodialis Eichl., Cissampelos tropaeolifolia DC., Anomospermumchloranthum Diels, Anomospermum steyermarkii Krukoff & Barneby,Hyperbaena domingensis (DC.) Benth., Orthomene hirsuta (Krukoff& Moldenke) Barneby & Krukoff, Orthomene schomburgkii (Miers)Barneby & Krukoff, Sciadotenia brachypoda Diels. All UV spectro-photometric analysis were performed using a modified version of apreviously published method (Basílio et al., 2012). Briefly, methanolextracts of dried leaves were prepared by ultrasound extraction for20 min at room temperature, and then filtered through membraneswith a pore size of 0.45 mm, modified from Basílio et al. (2012).
The UV/Vis spectra were recorded with a spectrophotometer(UV-1650PC, Shimadzu, Kyoto, Japan). For all absorbance measure-ments Quartz cells (1 cm) were used. The spectra were recordedin triplicate from 770 to 200 nm. The standardized procedure wasrepeated for all species and the data was automatically reduced toan ASCII file.
The spectra were normalized by setting the absorbance at770 nm equal to zero and subsequently mean centered. The datamatrix was processed by FITOPAC v.2.1.2 software. Finally, a prin-cipal component analysis (PCA) was performed using the methods

esults and discussion
natomic study
The leaf epidermis of C. pareira, in front view, presented cellsith curve to waved anticlinal walls on the glabrescent adaxial
urface (Fig. 1A and C), and waved and hairy on the abaxial sur-ace (Table 2, Fig. 1B and D). In transverse section, the epidermis of. pareira was uniseriate with tabular cells, and a thin and smoothuticle (Fig. 3A). Metcalfe and Chalk (1950), Porto et al. (2011) andudhakaran (2012) have reported this pattern of cell walls to C.areira. It was also recorded in other species of Cissampelos (Hongt al., 2001; De Wet et al., 2002; Porto et al., 2011), and other generaf Menispermaceae as Cocculus and Stephania (Metcalfe and Chalk,950). Only two samples from Brazil (CP6 and CPb), and two fromfrica (CP8 and CP9) showed thickened cuticle (Figs. 4E and 5C, E)
hat differed from the C. pareira pattern (Table 2). To Wilkinson1979), in general the presence and thickness of the cuticle isetermined by environmental factor and does not have taxonomic
mportance.Eight specimens identified as C. pareira displayed the leaf epi-
ermis pattern different from those known for this species. Twoamples from Brazil (CP6 and CPb) showed straight anticlinal wallsn the adaxial, and curve on the abaxial (Table 2, Fig. 4C and). According to Stace (1965), the features of anticlinal walls are
mesomorphic character, and environmental conditions such asumidity play a significant role in determining the pattern of anti-linal cell walls. These features also have been reported to varyn response to changes in light regimes by Rôc as et al. (2001) and
antuano et al. (2006).Four samples from Brazil, CP3, CP5, CPa and CPc (Table. 2,
ig. 4G), and three from Africa (CP7, CP8 and CP9) showed anpidermal papillae (Table. 2, Fig. 5A). The presence, number and dis-ribution of papillae constitute an important feature that has beensed to define boundaries at specific and generic level in many tax-nomic groups (Hong et al., 2001). According to Bone et al. (1985),he cell walls of the leaf epidermis with convex curvature would bedvantageous to increase the energy capture efficiency, which ismportant for plants that must survive at extremely low light lev-ls. Furthermore, papillae in the leaf epidermis minimize the areaf contact causing a very low adhesion of water on leaf (Ensikatt al., 2011).
Epicuticular waxes as tubules and clusters of tubules were con-rmed in SEM, in both surfaces of C. pareira (Fig. 2C and D), asreviously referred by Porto et al. (2011). The epicuticular waxeslso have taxonomic value in the characterization of the leaf epider-is, according to Barthlott et al. (1998). Moreover, the presence ofax tubules in leaf epidermis could be related to the higher water
epellency (Ensikat et al., 2011).The leaves were hypostomatic with anomocytic and anisocytic
tomata occurring simultaneously, both at the epidermal levelFig. 3A), however, the anomocytic type was predominant (Fig. 1D),hich corroborate with the pattern previously described to C.
areira by De Wet et al. (2002) and Porto et al. (2011). Simple bi-elled to many-celled trichomes were present on both surfaces ofhe leaf epidermis (Figs. 1A, B and 2A, B), which are common onhe leaf epidermis of some Menispermaceae species, according to
ilkinson (1978).
Dorsiventral leaves with adaxial mesophyll and a single layerf palisade was the pattern for C. pareira (Table 2, Fig. 3A). How-ver, bisseriate palisade was observed in five samples, being tworom Brazil (CP6 and CPb), and three from Africa (CP7, CP8, CP9) Ta

ig. 2. Cissampelos pareira (RL Fróes 30443), leaf epidermis in front view by SEM: (A)n the abaxial surface; (C) detail of the abaxial epidermis with epicuticular waxes, apicuticular wax; st, stomata; tri, trichome).
Table 2, Fig. 5C) According to Esau (1972), Levitt (1980) andozema et al. (1997), palisade and spongy parenchyma are tissuesnown to reveal responses related to light and soil water varia-ions. All samples showed 3–5-layered spongy parenchyma witharge intercellular spaces (Fig. 3A), and several collateral vascularundles distributed throughout the mesophyll.
The leaf margin was slightly curved toward the abaxial surfaceith a many-layered collenchyma and a single vascular bundle. Theorsiventral organization of the leaf mesophyll is characteristic toissampelos, according to Metcalfe and Chalk (1979) and De Wett al. (2002), and does not constitute an exclusive character of C.areira.
The midrib was biconvex, in transverse section, more promi-ent and rounded to the abaxial surface with a sub-epidermal–5-layered lacunar collenchyma, followed by the fundamentalarenchyma. The vascular system has a single vascular bundle with
sclerenchymatous ring at the middle portion, and 1–2 smaller vas-ular bundles at the base and apex (Table 2, Fig. 3B). Five samples,hree from Africa (CP7, CP8 and CP9) and two from Brazil (CP6 andPb) showed midrib with plane-convex shape, differing from theore common biconvex pattern characteristic of C. pareira (Table 2,
igs. 4D and 5D). In our studies, the morphology of the midrib inissampelos and other genera of Menispermaceae (in prep.), consti-utes an important feature to separate taxa at specific level, whichs also corroborated by studies of De Wet et al. (2002).
In transverse section, the petiole of C. pareira showed circularontour with uniseriate epidermis and simple long trichomes; theortex under the epidermis has continuous collenchyma similar tohe midrib; the vascular system is formed by 6–8 collateral vascular
undles (Fig. 3C–E), which are surrounded by a sclerenchymaticing at the middle portion (Table 2, Fig. 3D). Six samples (CP3, CP5,P6, CPa, CPb and CPc) showed 9–12 collateral vascular bundlesTable 2, Fig. 4E), thus differing from the pattern observed for C.al surface with long finger hairs; (B) detail of the wrinkled epidermis and trichomesle; (D) stoma in detail and epicuticular waxes on the abaxial surface (Legends: epw,
pareira and therefore suggesting these samples belong to differenttaxa.
According to Sinnot (1914), Metcalfe and Chalk (1950) andHoward (1979), the characteristics of the angiosperms have greattaxonomic significance because the environment does not influ-ence it. Moreover, the petiole vascularization is diagnostic todistinguish some genera and species and also has taxonomic impor-tance (Wilkinson, 1978, 1986, 1989). On the other hand, thesclerenchymatic sheath was also referred to C. sympodialis by Portoet al. (2008), and to other South African Cissampelos species by DeWet et al. (2002). It is common in vegetative organs of Menisper-maceae, especially in lianas (Carlquist, 1996).
Idioblasts were observed in the vascular tissue of the corti-cal parenchyma of the midrib and petiole and showed a positivereaction to alkaloids in all samples of C. pareira (Table 2, Fig. 3F).Differently, the samples CP3, CP5, CP6, CP8, CP9, CPa, CPb andCP5 showed no positive reaction to alkaloids (Fig. 5G and H).These results corroborate with existing chemical studies of Cis-sampelos (Semwal et al., 2014), as well as confirm the localizationof the production and/or accumulation of these compounds inthe leaf (Chowdhury, 1972; Cavalcanti et al., 2014). According toMenachery (1996) and Barbosa-Filho et al. (1997), the occurrenceof alkaloids can be a chemotaxonomic character of Menisperma-ceae.
Secretory cavities were observed at the leaf apex of two samplesfrom Africa (CP8 and CP9), and also in the midrib and petiole of eightsamples (Table 2, Figs. 4H and 5E, F), three from Africa (CP7, CP8 andCP9), and six from Brazil (CP3, CP5, CP6, CPa, CPb and CPc). Althoughthis character has been reported for some species of Cissampelos
and other genera of Menispermaceae (Metcalfe and Chalk, 1950,1979; Wilkinson, 1989; De Wet et al., 2002), it was never men-tioned before to C. pareira, and provides further evidence that thesesamples with secretory cavities belong to different taxa.

The results of the leaf anatomy of thirteen samples analyzeddentified as C. pareira, revealed that only five of these samples (CP1,P2, CP4, CPd and CPe), all from Brazil, showed a set of charactershat match the pattern described for C. pareira by Porto et al. (2011)nd Sudhakaran (2012), which are summarized here: hypostomaticeaf blades; anomocytic and anisocytic stomata with predominancef the first type at the epidermis level; epidermal anticlinal wallsurves on the adaxial surface, and wavy on the abaxial surface;pidermis with thin cuticle and simple uniseriate trichomes; dor-iventral mesophyll with uniseriate palisade parenchyma, with fewnd rare styloid cristals (Table 2, Fig. 4H); biconvex midrib; collat-ral vascular system; petiole with 6–7 vascular bundles; idioblasts

characters displayed by these samples allow to separate them intothree groups, which could belong to distinct and unidentified taxa(Table 2): Cissampelos sp1, CP3, CP5, CPa and CPc (Fig. 4A and B);Cissampelos sp2 (Fig. 4C–H), CP6 and CPb; and Cissampelos sp3, CP7,CP8 and CP9 (Fig. 5A–H).
Cissampelos sp1 and Cissampelos sp3 have secretory cavities,biconvex midrib, and epidermal papillae on the abaxial surface.However, they present distinctive characters: Cissampelos sp1 hasuniseriate palisade parenchyma, and the petiole with 9–12 vas-cular bundles (Table 2); while in Cissampelos sp3 the palisadeparenchyma is biseriate and the petiole has 6–8 vascular bundles.
On the other hand, samples of Cissampelos sp2 differs fromCissampelos sp1 and Cissampelos sp3 mainly by the anticlinal wallsof epidermal cells that are straight and smooth with thin cuticle
(Fig. 4C and D), without papillae. However, it shows a biseriatemesophyll and plane-convex midrib, similar to Cissampelos sp3,but different from Cissampelos sp1 that has an uniseriate palisade,and biconvex midrib.

The characterization of spectra was carried out by the anal-ysis of methanol extracts of specimens. Four distinct absorptionbands were observed (Table 3): Band I (�max 500–504.5 nm); BandII (�max 391.5–468 nm); Band III (�max 312.5–368.5 nm); Band IV(�max 223–291 nm).
In the interspecific analysis all analyzed species showed sim-ilar absorption for the bands I and III, which may be related tothe overlap of absorption in this region. However, in the region ofband II (�max at 403.5–410.0 nm), Cissampelos tropaeolifolia showed

Based on the data available, such absorbance can be related to thepresence of tropoisoquinoline alkaloids, which were already iso-lated from C. pareira (Morita et al., 1993), and is also common inother species of Cissampelos (Menachery, 1996).
The spectral data of the outgroup samples, A. chloranthum, A.

The principal component analysis of spectral data allowed theifferentiation of samples of C. pareira of African and Brazilianrigin mainly based on their score values at PC3. The spectra ofrazilian samples CP4 and CP6 showed proximity with the samplesf the African group, CP7, CP8 and CP9 (Fig. 8). The samples of C.areira specimens were close to C. tropaeolifolia and C. sympodialisith positive score values in the PC3 (Fig. 7B). It is worth noting a
roup of African (CP7, CP8 and CP9) and Brazilian samples (CP4 andP6) that, although similar, has spread throughout the dispersioniagram (Fig. 8). Based on the results, in general, the PCA analysisas able to delimit the species of Cissampelos analyzed.
The results showed that application of UV/Vis spectropho-
ometry is a valid technique for identifying Cissampelos samples,onfirming the observations already made for other angiospermsroups such as Asteraceae by Lonni et al. (2005) and Solanum byasílio et al. (2012).× PC3: PCA spectral profile (770–250 nm).
The chemical data corroborates with the anatomical featuresof C. pareira samples, which differentiates them from samples ofother species with the following characters: biseriate parenchyma,stomata above the level of the epidermis, presence of epidermalpapillae as well as secretory cavities in the mesophyll.
The principal components analysis (PCA) provided importantspectral information, which allowed the separation of African-tropical and Neotropical samples. These differences may be relatedto geographical distribution, considered by Griffin and Lin (2000)as an aspect that influences the chemical composition of plants.However, when analyzing chemical data together with anatom-ical characters, usually neglected in taxonomic studies, these
differences suggest that the studied samples belong to differenttaxa, probably in speciation, after being subjected to differentselection processes, with the development of adaptive charac-ters.N.M. Porto et al. / Revista Brasileira de Fa

onclusions
Characters of epidermal cells, mesophyll (palisade parenchymaayers), midrib shape, number of vascular bundles in petiole, secre-ory cavities, and the chemical results proved to be useful andistinctive to separate C. pareira from related species, providing andditional tool for its taxonomy, and quality control of their drugsomposed by leaves. Further chemical and taxonomic studies areeeded to enable the identification of all taxa, as well as to explainome variations in spectral and anatomical data to C. pareira andts related species.
